1, this supervising device combines zoom lens group and telephoto lens, and the switching of by plane reflection, putting mirror realizes the purpose of bilateral light path time-sharing multiplex.Logical light path one can be monitored large visual field scene; Logical light path two can be monitored remote scene.This device had both possessed all advantages of common zoom integrated camera, had again function of telescope concurrently, and carried out by zoom lens group the effect of looking in the distance that zoom can obtain different zoom ratios when looking in the distance pattern.
2, the image-forming module in this supervising device can be used on market existing zoom all-in-one or focus all-in-one, not only realizes standardization, and reduces secondary development period, and Installation and Debugging are very convenient, effectively reduce production costs.
3, the volume of this supervising device is little, its attached support equipment (as The Cloud Terrace, protective cover) is required low, has greatly reduced the cost of attached support equipment;
4, the utility model is simple in structure, design science is reasonable, can be widely used in the occasion of demand remote monitor, is particularly suitable for taking into account remote and in-plant monitoring, such as environmental inspection, on-site supervision, Well grab etc.
The accompanying drawing explanation
Fig. 1 is that the utility model is switched to the structural representation while taking the photograph the distance light road;
Fig. 2 is the structural representation of the utility model while being switched to common varifocal imaging light path.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of have a double light path supervising device of taking the photograph function far away, as shown in Figure 1, comprise housing 2, telephoto lens 1, common object lens 10, right angle roof prism 4, plane mirror 3, plane reflection pendulum mirror 9 and imaging device, the square box structure that described housing is six sealings, on the housing front panel, lower two ends vertical spacing respectively are shaped with form 12 and lower form 11, on correspondence, form is equipped with telephoto lens, corresponding lower form is equipped with common object lens, by support, the right angle roof prism is installed in the housing of corresponding telephoto lens, the plane mirror of downward-sloping 45 degree is installed at the inboard front panel of the housing of roof prism bottom, corresponding right angle, on the inboard base plate of housing below the corresponding flat catoptron, the hinge load is connected to plane reflection pendulum mirror, the anglec of rotation of this plane reflection pendulum mirror is divided into two grades, level 0 degree and 45 degree that are inclined upwardly, the inboard base plate of the housing rear portion of corresponding flat reflection pendulum mirror is equipped with imaging device.
In the present embodiment, described imaging device is processed output module 5 by the zoom lens group 7 connected successively, CCD/CMOS imageing sensor 6 and image and is formed, and wherein zoom lens group adopts the Varifocal zoom lens with aperture, after installation, can be regulated.This imaging device can be a varifocal integrated camera assembled, and also can use the integrated bare machine of existing zoom on market, so greatly reduces the secondary development period of product, improves versatility of the present utility model simultaneously.Use and do not need zoom if on-the-spot, can use the tight shot of proper focal length to replace zoom lens group.
Described telephoto lens adopts positive burnt convex lens and negative burnt concavees lens gummed to form, thus effectively color difference eliminating impact; Described common object lens are high window mirror thoroughly.
The implementation of described plane reflection pendulum mirror rotation action is: an end of this plane reflection pendulum mirror is fitted together by the inboard base plate hinge of pedestal 8 and housing, by gear, belt gear, drives the purpose that plane reflection pendulum mirror is realized the free end rotation.
The utility model can form the logical light path of two-way by the connection of above-mentioned parts:
(1) logical light path one: as shown in Figure 2, the rotation angle of plane reflection pendulum mirror is level 0 degree, object light directly enters zoom lens group, CCD/CMOS imageing sensor and image by common object lens and processes output module, and the larger scene in visual field can be absorbed in this path.
(2) logical light path two: as shown in Figure 1, object light is after telephoto lens, change path through the turnover of right angle roof prism and enter plane mirror, plane mirror reflects object light to plane reflection pendulum mirror again, plane reflection pendulum mirror 45 degree that are inclined upwardly now, enter zoom lens group after the reflection of plane reflection pendulum mirror, then obtain imaging picture clearly through CCD/CMOS imageing sensor and image processing output module.Now zoom lens group mainly plays the effect of eyepiece, therefore this light path is similar to the light path of telescopic system, suppose that in this light path, zoom lens group focal length now is f, the focal length of telephoto lens is fo, zoom ratio M=fo/f, so, in the situation that the telephoto lens focal length is certain, can guarantee can realize anamorphosis function in remote certain scope by the focal length of regulating zoom lens group.
Put mirror by plane reflection between above-mentioned two logical light paths and switched, plane reflection pendulum mirror, by transmission mechanism control, when plane reflection pendulum mirror is horizontal level, is selected logical light path one; When plane reflection is put the optical axis angle at 45 ° of mirror and zoom lens group, select logical light path two, now can automatically regulate the imaging effect (visual field and visual range are comparatively suitable) that zoom lens group reaches an optimum, regulate the multiple of looking in the distance as need and can suitably regulate zoom lens group, to obtain the effect of looking in the distance of different multiples.
Under default situations, use logical light path one to carry out imaging, will lead to light path one and be switched to logical light path two and carry out imaging in following situation: (1) receives the instruction that is switched to logical light path two imagings; (2) zoom lens group zoom still need to continue zoom to maximum.To lead to light path two in following situation is switched to logical light path one and carries out imaging: (1) receives the instruction that is switched to logical light path one imaging; (2) zoom lens group continues zoom and also can't carry out photo-quality imaging.Described photo-quality imaging refers to that logical light path one and logical light path two all prestore the optimal imaging point in advance, and this optimal imaging point also can be the parameter of preserving when zoom lens group is switched, and when switching back former optical path again, restores to the original state.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
